SEOUL - North Korea claimed that more than a million young people had signed up for or rejoined the army this week after Pyongyang accused Seoul's military of sending drones into its airspace.
Pyongyang on Tuesday blew up deeply symbolic roads and railways connecting the two Koreas after warning any further drone flights would be considered a declaration of war, and ordered soldiers on the border to prepare to fire.
Seoul initially denied sending drones, but Pyongyang claims it has "clear evidence" of official involvement in the campaign, which purportedly features anti-regime propaganda leaflets scattered over the North's capital.
"Millions of young people have turned out in the nationwide struggle to wipe out the ROK scum who committed a serious provocation of violating the sovereignty of the DPRK through a drone infiltration," the official Korean Central News Agency said, referring to both countries by their official acronyms.
It said more than 1.4 million youth league officials and youth and students across the country volunteered to join or rejoin the Korean People's Army on October 14 and 15.
North Korea already has lengthy periods of mandatory military service for all men, and has previously made claims of patriotic waves of enlistments at times of high tensions with Seoul or Washington.
While it remains unclear who is behind the drone flights, South Korean activists have long flown balloons carrying anti-Pyongyang regime leaflets over the border, a tactic that infuriates the North and which has responded by bombarding the South with trash-carrying balloons.
South Korean authorities in areas near the border with the nuclear-armed North are moving to prevent activists from launching balloons.
To protect its citizens, the provincial government of Gyeonggi will designate Yeoncheon, Gimpo and Paju "as special 'danger' zones where anyone trying to send leaflets to the North may be subject to criminal investigation", an officer from the Gyeonggi provincial goverment told AFP.
"The Gyeonggi Province considers the act of distributing anti-North leaflets to be a crisis-causing dangerous act that could cause a military conflict," the Gyeonggi government said in a separate statement.
